Genes affected

COLGALT1 (HGNC:26182): (collagen beta(1-O)galactosyltransferase 1) The protein encoded by this gene is one of two enzymes that transfers galactose moieties to hydroxylysine residues of collagen and mannose binding lectin. This gene is constitutively expressed and encodes a soluble protein that localizes to the endoplasmic reticulum. [provided by RefSeq, Dec 2015]

COLGALT1 (HGNC:):
